| 摘 要： | 采用澳大利亚源流域水量水质模型模拟东山小流域内2001-2010年9种不同土地利用类型产生的降雨径流及总氮和总磷的污染负荷,模拟结果为:流域内多年平均径流量为6 150万m3/a,总氮输出负荷为270 t/a,总磷负荷为22 t/a。模拟结果表明:水产养殖塘和高地茶果树是东山地区主要的营养物来源。通过三个情景方案的模拟,说明当地环境管理方案可以有效地削减入湖的营养负荷,其中第二个情景方案的削减量最大,总氮和总磷负荷分别削减了18%和25%。 |

| Abstract: | Using Source IMS water quantity and quality model to simulate rainfall runoff generation and TN and TP nutrients loads in Dongshan Peninsula though 2001-2010.According to the simulation,the average annual runoff was 61 500 000 m3/a,total nitrogen output load is 270 t/ a,total phosphorus load 22 t/a.The aquiculture pond and highland tea fruit is Dongshan area’s main nutrient source.Through three scenarios simulation,the local environmental management scheme can effectively reduce the nutrient load into the lake,the second scenarios’ reduction is the most,total nitrogen and total phosphorus load respectively by 18% and 25%. |
| Keywords: | Source IMS non-point source pollution load TN TP |
